WELIr-BAILING DEVICE.

Specification of Letters Patent.

Application filed May 7, 1913.

Patented Apr. '7, 1914. Serial No. veaeso.

To all whom it may concern Be it known that I, the undersigned, EARL E. Wns'r, a citizen of the United States, residing at Bridgeport, in the county of Lawrence and State of Illinois, have invented certain new and useful Improvements in ell-Bailing Devices, of which the following is a specification.

This invention relates to improvements in tools or appliances for the bailing out of deep wells, and has for its object to provide a tool or'impleinent of the character re ferred to which will be effective for use in wells or borings generally and in the raising of the well sediment regardless of the nature of its consistency.

My present invention consists of the new construction, combination and arrangement of parts, and the details of construction shown in the accompanying drawings, and described in this specification, and defined in the appended claims.

The several parts of the invention are designated by similar characters of reference applied thereto in the different views in the drawings, in which- Figure 1 is a side view of my improved well bailer complete. Fig. 2 is an enlarged vertical transverse sectional view of the body portion of the bailer as shown in Fig. 1. Fig. 3 is a view similar to Fig. 2, the valve members being shown in elevation. Fig. 1 is a vertical central sectional view taken in the direction indicated by the arrow 4: in Fig. 3.

The barrel or body portion of my improved bailer consists of the metallic tube 1 of the dimension substantially the same as those of ordinary bailer tubes, the same being about eight feet in height and about five inches in diameter. Secured to the top of the tube is a bail 2 consisting of a stout metal bar having its ends bolted or riveted to the walls of the tube. The valve provided for the bottom of this tube and designated herein as the foot valve, is of the new construction shown. The hollow body member 3 which is externally threaded, is screwed into the internally threaded bottom end of the tube 1, the edge of the shoulder 4 abutting against the bottom edge of the tube. The top portion of this body member is cone shaped; at each side of the neck 5 are open ings 6. The planed rims of these openings constitute smooth seats 7 upon which closure anchor trip member engage the bottom of 1 the body member 3 when the anchor trip is 5 raised, thereby limiting the extent of its up- 1 ward movement.

It is obvious that with the several parts occupying the positions as described the weight of the tube contents will maintain the valve plates at closed position. To cause a discharge of the tube contents the anchor trip is shifted upwardly; the valve plates are thus raised from their seats and the fluid contents of the tube will flow through the openings 6. Fluid contents of consistency that will not so readily pass through the valve openings have, however, to be dealt with. In prospecting operations, borings and well-drilling, quantities of sediment and residue accumulate in the well. This sediment assumes the form and consists of a liqueous mixture of sand, grit, dirt and small quantities of stone and earth and fragllTlQlltS of shale and well drillings; and the consistency of such liquid is such that someltimes it will not readily enter the valve iopenings of the bottom of the bailer tube. To provide a mechanism whereby the well contents of the heavier consistency described may be raised, I combine with the tube 1 and the foot valve, a plunger member and connected parts of the construction and arrangement shown.

M designates a hollow body member of diameter to fit freely in the bores of the tube 1. Between the ring 15 and the bottom of the body member is secured the annular packing ring 16. The top of this hollow body member is cone shaped and between the openings 17 is the neck 18. The planed rims of these openings constitute smooth seats upon which the valve plates 19 are adapted to rest. These valve plates 19 have ears formed on their under sides and are pivotally connected to the arms 20 of the anchor trip 21 and which arms engage loosely the neck 18.

22 designates a forked arm whose ends are secured to the body member 14:. The head end of this arm 22 has loose connection with the lower head of the link member 23.

Fig. 2, the upper end of the link will rest on the bail 2; the anchor trip 21 occupying its normal position.

My improved bailing device complete appears as shown in Fig. 1. The rope having connection with the usual raising and lowering mechanisms, is connected to the upper end of the link 23. When lowered into the well contents that are to be raised the pres sure of the well contents unseats the valve plates 8 and the tube 1 is soon filled. The device is then raised and swung aside and when lowered to a suitable trip block located near the well and upon which the anchor trip makes contact, the anchor trip is raised and the valve plates 8 are unseated the foot valvebeing thus opened and a free outflow of the tube contents is permitted.

It will be understood that in instances as just described when the Well contents are comparatively clear and capable of entering through the foot valve freely, the plunger member performs no function. However it is the case in well cleaning that sooner or later there is difficulty to be encountered in removing and bringing up the thicker or more viscous liquid or substances. It is in this connection that the plunger member and its connections come into play. The device is lowered in the manner hereinbefore described. WVith the contact of the tube 1 with the sediment formation or residue, and its movement downwardly being arrested, the plunger member then moves downwardly in the tube; the air in the tube passing out underneath the valve plates 19. The plunger member having reached the bottom of the tube, the operator then causes same to be raised. With the upward movement of the Copies of this patent may be obtained for In one arm or side of the link 23 is pro vided an opening 23 the ends thereat being secured by a suitable locking means. By this arrangement it is practicable to remove the plunger member and link from its con-- nection with the bailer tube; thereby facilitating the cleaning of the tube, or the re pairing of any of the parts, and alsowhereby the bailer tube may be used without the plunger member if desired.

That I claim as m invention, and desire to secure by Letters Patent, is r 1. 'In a bailer device, the combination of a tube, a bail secured to its top, a hollow body member secured in the bottom-of the tube its top being cone shaped and provided with a pair of openings there bein a neck between same, an anchor trip member hav-' ing arms to engage the said neck, and valve plates to cover said openings and having their undersides connected loosely to the said arms.

2. In a bailer device, the combination of a tube, a bail secured to its top, a hollow body member secured in the bottom of the tube its top being cone shaped andprovided with a pair of openings there bein a neck between same, an anchor trip member hav ing arms to engage the said neck, valve plates to cover said openings and having their undersides connected loosely to the said arms, a link having engagement with the aforesaid bail, a piston head connected to the bottom end of the link, and a valve in the piston head. i

In testimony whereof I affix my signature in presence of two witnesses.
